Quality Control
The PMI test verifies that the floating ball valve’s materials match the specific chemical requirements, confirming the correct composition before production begins.
PMI Test
The sealing test evaluates the floating ball valve for leaks under pressure, confirming it can hold fluid securely without escaping during use.
Sealing Test
The low emission test measures how much gas or liquid leaks from the floating ball valve, helping to minimize environmental impact during operation.
Low Emission Test
The impact test checks how well the floating ball valve withstands force, showing its ability to handle physical shocks without damage.
Impact Test
The dimension inspection checks the floating ball valve’s size and shape using precise tools, confirming it meets design standards accurately.
Dimension Inspection
The painting thickness test measures the protective coating on the floating ball valve, helping to protect it against corrosion and wear over time.
Painting Thickness Test
The PT test applies a special liquid to detect small surface cracks or flaws on the floating ball valve, revealing any hidden weaknesses.
PT
Material inspection examines the quality of the floating ball valve’s raw materials, confirming that only high-quality components are used in production.

Floating Ball Valve Design Features
Blowout Proof Sten
Internally inserted, "backseated" stem assures fire safety and blow-out prevention by retaining stem in the valve at all pressure.
Stem Journal Lubrication
All valves incorporate external stem lubrication. A vented weather seal allows safe pressure relief in the event of excessive grease gun pressure.
Antistatic Device
A conductive spring, graphite washer, and spring-loaded pins ensure antistatic continuity throughout the valve for 1" to 4" bores (CL.600, 900, 1500).
Antistatic Device
1"bore-4"bore, CL.600,900 &1500 use spring-loaded pins between the ball,stem,and body to provide antistatic continuity throughout the valve.
Firesafe Seat Sealing
In the event of fire and seat destruction, ball floats downstream to effectively provide metal-to metal seat sealing.
Pressure Sealing
An integral seat lip ensures a tight seal at low pressure and adjusts at higher pressure for full contact, providing low torque and long-lasting performance.

Cast Floating Ball Valve
STRUCTURAL FEATURES
Special Seat Design
The floating ball valve features a flexible seal ring structure. At lower medium pressures, the contact area between the seal ring and the ball is smaller, creating a higher sealing ratio at the contact point. This design provides reliable sealing.
As the medium pressure increases, the contact area between the seal ring and ball expands due to the elastic deformation of the seal ring, allowing it to withstand higher medium thrust without damage.
Fireproof Structure Design
In the event of a fire, the seat ring, typically made of PTFE or other non-metal materials, may decompose or be damaged under high temperatures, leading to increased leakage. To address this, a fireproof seal ring is placed between the ball and seat. If the valve seat burns, the medium pushes the ball rapidly toward the downstream metal seal ring, forming an auxiliary metal-to-metal sealing structure.
Additionally, the middle flange sealing gasket is made of a metal-wound gasket, which maintains sealing even under high temperatures. The fireproof structure design of the floating ball valve complies with standards such as API 607, API 6FA, and BS 6755.
Reliable Sealing Of Valve Stem
The valve stem is designed with a shoulder at its base, preventing it from being blown out by the medium, even under extreme conditions such as abnormal pressure rise within the valve cavity or gland plate failure. To prevent leakage after stem packing burns during a fire, a thrust bearing is placed at the contact point between the stem shoulder and the body, forming a reverse sealing seat.
The sealing force of this reverse seal increases with the medium pressure, ensuring dependable stem sealing under various pressures, thus preventing leakage and avoiding the spread of accidents.
The stem uses a V-type packing sealing structure, which effectively converts the pressing force and medium force of the gland into the sealing force of the stem.
For additional reliability, a disc spring-loaded packing pressing mechanism can be used, based on user requirements.
Anti-static Structure
The ball valve is equipped with an anti-static structure that incorporates a static electricity discharge device. This device forms a direct static channel between the ball and body or creates a static channel through the stem, allowing static electricity generated by friction during the opening and closing of the ball and seat to discharge through the pipeline.
This feature helps prevent fires or explosions caused by static sparks, enhancing system safety.
Lock And Misoperation Prevention
The manual ball valve can be locked in either the fully open or fully closed position. A 90° open and close positioning piece with a lock hole is designed to prevent misoperation caused by unauthorized handle operation. It also helps avoid accidental valve opening or closing due to pipeline vibrations or other unpredictable factors.
This feature is particularly effective in environments with flammable and explosive substances, such as oil, chemical, and medical pipelines or field tubing. The handle installation on the stem’s head features a flat design. When the valve is open, the handle aligns parallel to the pipeline, providing accurate open and close indications without error.

4 Considerations When Buying Floating Ball Valve
01
Temperature Compatibility
Temperature compatibility is crucial when selecting a floating ball valve. Check that the valve can withstand the temperatures it will be exposed to during operation. Valves used in high-temperature applications need to be made from materials that can handle the heat. This prevents valve failure and maintains safety.
02
End Connections
The type of end connections on the valve is another key factor. Common types include threaded, flanged, and welded connections. For example, a flanged connection is often used in high-pressure applications because it provides a strong and leak-free seal. Selecting the right connection type guarantees a secure and reliable installation.
